CVE-2025-34071 gfi vulnerability CVSS: 0 02 Jul 2025, 14:15 UTC

A remote code execution vulnerability in GFI Kerio Control 9.4.5 allows attackers with administrative access to upload and execute arbitrary code through the firmware upgrade feature. The system upgrade mechanism accepts unsigned .img files, which can be modified to include malicious scripts within the upgrade.sh or disk image components. These modified upgrade images are not validated for authenticity or integrity, and are executed by the system post-upload, enabling root access.

CVE-2025-34070 gfi vulnerability CVSS: 0 02 Jul 2025, 14:15 UTC

A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows unauthenticated remote attackers to perform privileged operations. The GFIAgent service, responsible for integration with GFI AppManager, exposes HTTP services on ports 7995 and 7996 without proper authentication. The /proxy handler on port 7996 allows arbitrary forwarding to administrative endpoints when provided with an Appliance UUID, which itself can be retrieved from port 7995. This results in a complete authentication bypass, permitting access to sensitive administrative APIs.

CVE-2025-34069 gfi vulnerability CVSS: 0 02 Jul 2025, 14:15 UTC

An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.

CVE-2025-34491 gfi vulnerability CVSS: 0 28 Apr 2025, 20:15 UTC

GFI MailEssentials prior to version 21.8 is vulnerable to an XML External Entity (XXE) issue. An authenticated and remote attacker can send crafted HTTP requests to read arbitrary system files.

CVE-2025-34489 gfi vulnerability CVSS: 0 28 Apr 2025, 19:15 UTC

GFI MailEssentials prior to version 21.8 is vulnerable to a local privilege escalation issue. A local attacker can escalate to NT Authority/SYSTEM by sending a crafted serialized payload to a .NET Remoting Service.

The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2025-2975 gfi vulnerability CVSS: 4.0 31 Mar 2025, 04:15 UTC

A vulnerability was found in GFI KerioConnect 10.0.6 and classified as problematic. This issue affects some unknown processing of the file Settings/Email/Signature/EditHtmlSource of the component Signature Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2024-52875 gfi vulnerability CVSS: 0 31 Jan 2025, 08:15 UTC

An issue was discovered in GFI Kerio Control 9.2.5 through 9.4.5. The dest GET parameter passed to the /nonauth/addCertException.cs and /nonauth/guestConfirm.cs and /nonauth/expiration.cs pages is not properly sanitized before being used to generate a Location HTTP header in a 302 HTTP response. This can be exploited to perform Open Redirect or HTTP Response Splitting attacks, which in turn lead to Reflected Cross-Site Scripting (XSS). Remote command execution can be achieved by leveraging the upgrade feature in the admin interface.

Race condition in VIPRE Antivirus Premium 4.0.3272 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute

CVE-2005-3182 gfi vulnerability CVSS: 7.5 20 Oct 2005, 10:02 UTC

Buffer overflow in the HTTP management interface for GFI MailSecurity 8.1 allows remote attackers to execute arbitrary code via long headers such as (1) Host and (2) Accept in HTTP requests.
